Abstract : Reported is a description of a method of calculating the harmonic vibrations of elastic rectangular plates which are freely supported at two edges and are reinforced vertically with eccentric ribs. First the plate edge shear forces for the bending and shear stress states, as well as the loads on the ribs, are determined for unit displacements in general form. Once these values have been determined, four equations can be set up for each rib, which contain the requirement that for compatible displacements of ribs and plate edges the plate edge forces coming from the plates adjoining a rib and the external loads must be equivalent to the forces which deform the rib.
